iPhone stuck on Apple logo + spinning wheel
 

I have an iPhone 3Gs, running on 4.1 now, (before this all it was on 3.1.3)
Since last night it started to act strange.. random reboots, very slow.. etc

I know how to get it in DFU mode, and yes I can restore, but even after it restored with official firmware, it still wont get further than the Apple logo + spinning wheel..
iTunes says that my SIM is locked with a PIN, and that I need to unlock it, but since my phone wont pass the Apple logo + spinning wheel..

Please help, I'm desperate currently.

Thanks in advance!

try recovery mode instead of DFU and try restore again but as u say that u already has 4.1 then i guess ur phone is factory unlocked or it won't be unlocked

i also try on recovery mode but same i know it is not unlocking but there is problem

check sticky threads about SHSH way and if u have shsh on cydia try restore the version of shsh and post results
